Kalles Kaviar

" A very Swedish taste"

Hmmm.  How do I describe Kalles Kaviar.  It is a  kind-of salty, kind-of fishy spread.
First marketed in 1954, it is, I think, the kind of food that although not particularly good, Swede's have grown up eating it and they like it.  I don't think it is bad, but I can't exactly recommend it.
Anyway, what is great is that the company that produces it makes fun of it.  Their current advertising campaign takes them around the world, giving our free taste samples.

The smiling Kalles Kaviar salesman sets up his samples in a city square and happily and hopefully shares his Kalles Kaviar.  But inevitably, the innocent sampler tastes the Kaviar and then tries to politely swallow it.
You can see some of the commercials on YouTube.
Just to get you started, here is the link to Kalle in Schweiz (Switzerland).

I saw an advertisement last winter that read something like,

"Kalles Kaviar.  .000003% of Spaniards can't be wrong."  : D
